fix(runtime): re-read domain.active/domain._stack instead of serving a cached first read

[TheHypnoo]

Summary

Restores test-parity/node-suite/domain to its 18/48 baseline floor (13/48 on main). The five regressed tests are bind-call-contract, enter-duplicate, enter-exit-active, intercept-call-contract and run-nested-restore.

Root cause

Bisected (good 78ccb596b, bad main) to aaa3ba534, "fix(module): complete Node 26 parity for node:module" (#7312). That commit added an ESM export snapshot cache for native-module properties (NATIVE_ESM_EXPORT_VALUES). The cache memoized the first read of domain.active / domain._stack, which are live values answered by the domain dispatch on every access. After that first read they stayed frozen:

const d = domain.create();
d.enter();
domain.active;                 // first read, gets cached
d.exit();                      // pops the stack correctly
String(domain.active);         // node: "undefined", perry: "[object Object]"

Fix

constants::native_module_constant_is_live marks those properties as live, and native_module_export_value neither reads nor writes the snapshot cache for them. Real constants keep the cached path.

Validation

• node-suite (Node 26.5.1): domain 13 → 18/48, exactly the 5 regressed tests. No drops elsewhere: module 58/60, events 70/70, process 104/105, util 88/88, globals 119/122. Domain also gives 18/48 in CI (auto-optimize) mode.
• New test-files/test_gap_domain_active_stack_live_reads.ts fails before the fix and matches Node after it.
• cargo test --release -p perry-runtime native_module (37/37), cargo fmt --check, check_file_size.sh, addr_class_inventory.py and gc_runtime_root_holders.py all pass.

The other 30 domain gaps are pre-existing: Domain is a bare handle, not a class. They are out of scope here.

Summary by CodeRabbit

• Bug Fixes
  • Fixed stale reads of domain.active and domain._stack when using the default node:domain import. These properties now reflect the current domain state each time they’re read.
  • The change applies to the default import; require("domain") and process.domain behavior is unchanged.

📝 Walkthrough

Walkthrough

Native ESM export resolution now bypasses snapshot caching for domain.active and domain._stack. A diagnostic test reads these properties around domain entry and exit. The changelog and version records are updated.

The PR advances both release-version fields, which the repository reserves for the maintainer to update at merge time. Restore the previous values before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 13814

The two domain properties now reflect current state instead of a first-read snapshot. No new privilege or access path was identified, though some lifecycle and import-compatibility behavior remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — A script that already reads native domain exports can observe current domain state on subsequent reads. The changed predicate supplies no new export or independently reachable privileged operation.

Trust Boundaries and Controls

• observed — For namespace reads, the user-override check remains before cache selection and dispatch; the change does not bypass that precedence control.

Resilience and Maintainability Implications

• inferred — Domain handles are inserted into a separate common-handle registry, so removing an export snapshot does not by itself remove their payloads. Thread-exit release rules and cross-thread lifetime were not fully verified.
